For each description write the appropriate region of the brain 1. Coordinates skeletal movements to produce smooth motion   2. Contains a structure that produces cerebrospinal fluid   3. Includes the thalamus, epithalamus, and hypothalamus   4. Secretes hormones and regulates non-intellectual functions such as emotions and sleep-wake cycles   5. Sorting and relay station for sensory information                                                                                                  6. Relays signals and keeps you "alert and alive"

Median nerve:  show how it branches from the brachial plexus, travels deep to the clavicle, distally down the anterior brachial and antebrachial regions, and eventually passes through the flexor retinaculum to innervate the wrist flexor muscles. Obturator nerve:  show how it branches from the lumbar plexus through the obturator foramen to innervate the muscles of the medial thigh, i.e., gracilis and adductors. Sciatic nerve:  show how it branches laterally from the sacral plexus at the intervertebral foramen between L5 and S1 and then pass through the greater sciatic notch to the posterior thigh to innervate the hamstrings. Show anterior and posterior image that show the plexus from which the nerve is derived, its pathway though the body, and to the anatomical area where it innervates skeletal muscles.  Show either by drawing or using a skeleton model.
